I don’t know about the new ATR72’s, but ex-Finnair/Aero ES-KRA (cn 126) got new registration some days ago. It is now EI-REJ. So it will be “new” ATR72 for Aer Arann? I don’t know if it already has left or is there still some test to do before delivery.
I took photos of the plane at May 9th when it was flying some test flights, and I think it still has same spectacular colour scheme. Only registration is changed.
